Matcha tea has become one of the most popular “health luxury” beverages on social media due to its antioxidant-rich benefits. However, it has recently sparked debate over its effects on hair health, following claims that excessive consumption may lead to hair loss.

The controversy escalated after a skincare entrepreneur shared her personal experience, stating that she noticed hair loss after drinking too much matcha. This sparked widespread discussions about the safety of the beverage.
Nutrition Experts’ Opinion
Rob Hobson, a nutrition expert and spokesperson for Bio-Kult, confirmed that matcha does not directly cause hair loss. He explained that the concern lies in tannins found in tea and nuts, which can inhibit the absorption of plant-based iron when consumed in large amounts, according to Mirror.
Hobson added that matcha contains higher tannin levels than traditional tea, but the effect remains limited if consumed in moderation—especially for individuals with iron deficiencies, such as vegetarians, pregnant women, or women in the pre-menopause stage.
Experts recommend consuming matcha away from iron-rich meals and pairing the diet with vitamin C-rich foods to improve absorption.
Proven Benefits of Japanese Green Tea
Studies show that matcha is rich in polyphenols like EGCG, which promote healthy gut bacteria, reduce inflammation, and improve metabolism. Its antioxidants also help protect hair follicles and support healthy hair growth.
Temporary vs. Permanent Hair Loss
Hair specialists emphasize that matcha does not cause permanent hair loss. In some cases, temporary shedding may occur due to reduced iron absorption, but hair follicles remain intact, and hair regrowth occurs once the underlying cause is addressed.
Risks of Excessive Consumption
Experts warn that overconsumption of matcha can lead to insomnia and sleep disturbances due to caffeine, as well as digestive or nervous issues such as stress and tremors. Rarely, it may slightly increase the risk of kidney stones due to its oxalate content.
Tips for Maintaining Healthy Hair
Beauty experts recommend a daily hair care routine that includes:
Reducing the use of heat styling tools.
Avoiding tight hairstyles.
Using silk or soft cotton hair ties.
Avoiding excessive brushing.
Using nourishing shampoos and conditioners to maintain hair health.
